Excellent! The best mobile router for now.
Compatible with all kinds of 4G operators (Tested with SKT, KT and LG U+ MediaLog SIMs.)
Especially Manager App can handle Unicode SMS messages. Very impressive.
It took only 3 days, 3 days, to receive the order after receipt of payment (3/18). I am using the LG U + wormhole, and when I turn on the power, it automatically goes to the network and the internet is good! I was a bit worried because I did not have a LG main in the supported frequency band and only support the secondary network frequency, but the test result was OK and I was impressed with the battery that lasts all day. I bought it for overseas trip but it is useful for data sharing in Korea.
